Direct connection 80 A

Operating instructions

• This family of metering equipments provides the essential measurement capabilities required to monitor a single phase electrical installation.
• There are 3 models, mainly distinguished by the type of remote communication: ( *) certification parameters: 0.25-5 (80) A, Class B, 230 VAC 50 Hz,-25 °C … +55 °C, 4 Quadrants, 2 Tariffs.
• Active Energy Class B (according to EN-50470) and Reactive Energy Class 2 (according to IEC 62053-23)
• Direct connected (up to 80 A)
• Backlightet LCD display and 3 push-button keys (to read Energies, V, I, PF, F, P, Q and to configure some parameters)
• Display with 8 digits.
• Self supplied (by the input voltage itself)
• 2 DIN modules width (36 mm)
• 2 Tariffs controlled by a 230 VAC digital input
• epending on the models:
  – 2 S0 standard low voltage pulse outputs, or
  – communication via Modbus RTU or
  – communication via M-Bus (1 unit load)

RISK OF ELECTRIC SHOCK, BURNS OR EXPLOSION
This device must be installed and maintained ONLY by qualified and duly authorized personnel.
During its installation, be sure there is no voltage applied.

Display

• Energy value
• kWh / kvarh display
• Running tarif, called tarif
• Energy value “Partial”
• Precision control LED

Commands

• Scroll Key: This key is used to scroll pages and to modify parameters value. Its pushing is accepted only if it is shorter than 1.5 second.
• OK key: This key is used alone to enable a new menu function or to confirm a parameter value during its modification. Its pushing is accepted only if shorter than 1.5 seconds
• ESC key: This key is used alone to exit from a sub-menu, to cancel a parameter modification or to go back to the main page. In these cases, its pushing is accepted only <1.5 seconds
• A long pushing (>1.5 seconds) of the “ESC key” is used in the Partial Energy Registers Pages to reset their values.
• Push these 2 keys together, for at least 1.5 seconds, to enter into the Configuration Menu

Symbols

Device Switch-on and Main Page

Main Page:
This page appears not only at device switch on, but also in case for 30 seconds no key is pushed. The value is the sum of 2 registers:
Imported Act. Energy Tariff T1 + Imported Act. Energy Tariff T2. (or, alternatively, the sum of the Exported ones).

Display Back light

• If no button is pushed for 40 seconds, the display goes back to the Main Page and the backlight is switched off.
• The first button pushing does not change the page but is used to switch the backlight on.

Multivalue Parameters Modification
In this example the Parity value is changed from None to Even. In any moment, push the “ ” key to stop the modification

Numeric Parameters Modification
In this example the Address value is modified from 167 to 18.

Diagnostic Message

Error Condition
If the display shows these messages, the meters has got a malfunction and must be replaced.

Service and Maintenance

It should not be necessary to recalibrate device during its lifetime as it is an electronic meter with no moving parts with electronics and voltage and current sensors that do not naturally degrade or change with time under specified environmental conditions. If a degradation in the performance is observed the device has probably been partly damaged and should be sent for repair or exchanged.
If the meter is dirty and needs to be cleaned, use lightly moistened tissue with a water based mild detergent. Make sure no liquid goes into the meter as this could damage the meter.

Applications

Please read this important information!
Intended Use / Use for Intended Purpose
The instrument is a digital multifunctional energy meter certified in accordance with MID. Integrated 4-quadrant measurement permits measurement of energy import and export.
Thanks to MID certification, acquired data (display) can also be used for the purpose of billing energy costs to third parties.
Via integrated communication interfaces, the values are also forwarded to superordinate management systems. Protection against tampering is provided through adequate measures (tamper-proof cover).
Safety of the operator, as well as that of the instrument, is only assured when it’s used for its intended purpose
Use for Other than Intended Purpose
Using the instrument for any purposes other than those described in the product documentation is contrary to use for intended purpose.
Liability and Guarantee
Gossen Metrawatt GmbH assumes no liability for property damage, personal injury or consequential damage resulting from improper or incorrect use of the product, in particular due to failure to observe the product documentation.
Furthermore, all guarantee claims are rendered null and void in such cases.
Nor does Gossen Metrawatt GmbH accept  any liability fordata loss.
Scope of Delivery
